Most automobile firms have now introduced new forms of work organization on the shopfloor, that often give workers a great autonomy in decision-making. How far do these changes result in new representations of the factory, work, and organisational restructuring within the workshop? In the Taylorist system workers considered their work a hardship, and depreciated their status in the firm. Their everyday behaviour was marked therefore by a will to cooperate, a sense of fraternity and a solidarity inherent to work. Because of that will the new politics of working organization implemented in the factories lead to a loss of workers' traditional solidarity and facilitate internal competition and discrimination towards less productive workers?
